A Balanced Approach to Normalizing Bus Operational Data for Performance Benchmarking Purposes
, 91st Transportation Research Board Annual MeetingPeer organizations in a performance benchmarking group are usually carefully selected based on similar characteristics such as the type of services offered, operational characteristics and density of the service area. These similarities enable organizations to compare performance once their operational data are normalized. The most commonly used normalization factors for the demand side output are passenger boardings and passenger kilometres. For the supply side output these are vehicle kilometres and vehicle hours. Through seven years of experience in the International Bus Benchmarking Group (IBBG) a better understanding of differences in service characteristics between ‘similar’ peers has been achieved. It became clear that relative performance can often not be concluded from a performance indicator normalized in one dimension. Variety in commercial speed, trip length, vehicle capacity, vehicle weight and network efficiency results in the need for a multi dimensional or balanced approach to data normalization. This paper quantifies the variety within these operational characteristics and provides a framework for benchmarking practitioners and policymakers that suggests applicable combinations of denominators for a balanced normalization process. This paper further describes how alternative normalization factors such as revenue service planning capacity kilometres and total tonne kilometres have improved comparability of Key Performance Indicators (KPIs).

A meta-analysis of the impact of Rail Projects on Land and Property values
The literature on land/property values demonstrates large variability in the estimated change in values arising from rail investments. This study conducts a meta-analysis on empirical estimates for 102 observations on the same. The factors that produce significant variations include the type of land use, the type of rail, rail maturity, the distance to stations, the geographical location, accessibility to other modes, methodological characteristics, and whether the impacted area is land or property. On the other hand, we observe that changes in purchase price and rent values are statistically indifferent, that there is no evidence of change in values over time nor due to the location of land/property within the city, and that including property and neighbourhood characteristics in the model do not change values significantly. Publication bias tests are performed and show that although researchers tend to report positive and negative results, they tend to be biased towards significant estimates.

Managing strategic risk – the worldwide experience of metros
, Proceedings of the Institution of Civil Engineers - Management, Procurement and Law, Vol: 164, Pages: 173-180, ISSN: 1751-4304<jats:p> This paper is concerned with the management of many of the world’s largest metros (mass transit railways). It describes how co-operation between operators has over 16 years led to continuous improvements in metro performance. In recent years, however, it has become clear that the complexities of metro systems are not always understood by stakeholders, and an increasingly uncertain future poses major challenges for proactive metro management. Research has concluded that the implementation of strategic risk management holds promise for future improvement, where risk is defined to include both downside impacts and opportunities. A risk guide has been developed to assist operators to implement effective practices. This paper is written to share these experiences in this sector, in the expectation that there may be lessons of wider interest. </jats:p>
